Application filed August 10, 1892- Serial No. 442,642. (No model.)

- State of California, have invented anew and useful Improvement inSchool-Room Gymnastic Apparatus, of which the following is aspecification.

My invention relates to gymnastic apparatus consisting in a series ofside supports con-.

, hand, chest and parallel bars arranged to furnish to all the pupils ina school room facilities for gymnastic exercise at the same time underthe View and personal direction of the teacher. Such apparatus isdetailed in my application for Letters Patent filed in the United StatesPatent Office May 2, 1892, Serial No.

The object of my present invention mm increase the convenience of suchgymnastic apparatus with relation toadjusting it into p0- sitionfor useand removing it outof the way when not in use. e

My present invention consists in the 'com-,

bination of the school desks which fornnthev side supports for the bars,the series of short hand, chest and parallel bars secured thereto bymeans which allow the bars to be adjusted in their vertical and lateralposition andsuch means for securing such bars to their respect ive desksor side supports. I r

The accompan-yingdrawings illustrate my invention. r t v e Figure l isanelevation of the upperv portion of the ends of two of a series ofdesks provided with my invention showing the same arranged. in positionfor use. Fig. 2 shows one of the bars thrown into the position it isdesigned to occupy whennot in use. Fig.3.

the arm 0 and secure it when it is inserted between the guides or lugsff'. .As shown, I the arm is provided with a series of holes 72. harranged in two series of three each to respectively receive the boltwhen the arm is elevated into different position as indicated indottedlines in Fig. 1'. Thehinge lugsc'to which the arm is hinged areprovided with two'pintle receiving holes j j in which re-' spectivelythe pintle k is inserted to pivot the arm in place. These two holes jjand the double line of holes h and h allow of vertical and'lateraladjustment of the bars to accombolts or screws Z Z to the desk, and isprovided withthe pivot andlockinglugs t" and f. It is to be understood,however that it would be no departure, from the spirit of my inventionto apply. the lugs directly to the frame'of the desk by casting themintegral therewith.

, In practice the school desks are provided with the pivot and lockingand guide lugs and the bars are pivoted in placeand when not in "use areallowedto hang down as indicated in Fig. 2 and are thus outof the way.Whenit is desired to use the gymnastic apparatus the bars are drawnintotheir upright positionas shown in Fig. 1 and are locked in the properposition by the'spring bolt If the pupil desires the bars to bewideapart the arms are locked in the position indicated-by dotted linesin Fig. 1. If they arethen'toolow, the

pintles is are removed, the bolts withdrawn and the arms 0 C are raiseduntil the pintle holes in the ends thereof (not shown) register with theupper pintlehole j when the pintle is inserted therethrough and the armsare locked by the bolt passing through a bolt hole of the lowerseries h.The pintle hole in the pivoted end of the arm is not shown as itsposition is clearly indicated by the pintle k.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination set forth of the series of school desks; the seriesof hand, chest and parallel bars secured to the ends thereofrespectively by means which allow the bars to be adjusted in theirlateral position, with relation to their respective desks and such,

' locking devices attached to such desks and arranged respectively tosustain such arms in an elevated position and to release themfrom suchposition.

3. The combination of the side support; the hinge lugs and the lockinglugs secured thereto; the arm provided at one end with the hand bar andpivoted at the other end to the hinge zc lug and provided with the boltreceiving holes; the locking lugs secured to the side support and thelocking bolt secured to the lugs and adapted to be inserted into suchholes.

'4. The combination of the side support; the hinge lugs provided withthe pintle holes jj; the arm provided with the pintle hole at its lowerend and with the hand bar at the other end and provided withintermediate double series of bolt receiving holes h h; the locking lug,secured to the side support and the locking bolt arranged to enter theholes to sustain the arm.
